N64 Rumble Pak perfect prison tattoo gun

A Kotaku reader, and prison guard extraordinaire, recently wrote in to talk about prisoners and their love of video games. Turns out, some U.S. prisons provide inmates with money to acquire video game systems as a reward for their hard work. This made the prison guards' jobs that much more difficult, though, as inmates would use the video game systems and various components to create things that weren't intended with their design.

For example, inmates would take the motor out of the N64 Rumble Pak and in combining it with some ink and a needle, could fashion it into a makeshift tattoo gun. We imagine many of the convicts on the receiving end of such a tattoo weren't getting Mario's face put on their body.
